Group 17 and 18 elements exhibit distinct properties due to the number of valence electrons present in their atomic structures. These elements, known as halogens, occupy the p-block region of the periodic table and exhibit characteristics that differentiate them from other elements.
The properties of Group 17 elements, often referred to as alkali metals, can be attributed to their low ionization energy and strong reducing power. These elements have a tendency to lose one or more valence electrons, resulting in a positive charge. This characteristic enables them to form positive ions, which are highly reactive.
In contrast, Group 18 elements, known as halogens, exhibit unique properties due to their highly stable electron configurations. These elements have a complete outer shell, indicating that they are unable to lose or gain valence electrons easily. Consequently, they tend to be unreactive, with a lower tendency to form negative ions.
The elements of Group 17 and 18 elements exhibit contrasting chemical behavior. Alkali metals are highly reactive, readily forming ions, while halogens are comparatively unreactive, with a higher electronegativity and lower ionization energy.
These properties are essential in determining the chemical behavior of these elements and are crucial in various fields, including chemistry, biochemistry, and materials science
